You can install vCenter Single Sign-On, the vSphere Web Client, vCenter Inventory Service, and vCenter Server together on a single host machine by using the vCenter Server Simple Install option. This option is appropriate for most deployments.

Users can log in to vCenter Server only if they are in a domain that has been added as a vCenter Single Sign-On identity source. vCenter Single Sign-On administrator users can add identity sources from the vSphere Web Client.

The required vCenter Server Java Components (JRE) are installed or upgraded silently when you install or upgrade vCenter Server. You can also install or upgrade vCenter Server Java Components separately.

As an alternative to installing vCenter Server on a Windows machine, you can download and deploy the VMware vCenter Server Appliance. The vCenter Server Appliance is a preconfigured Linux-based virtual machine optimized for running vCenter Server and the associated services.
